Yet, according to my brain, my dad first took me to see Star Wars one night after school, on a warm, early summer, evening, and I distinctly remember being in my school uniform.
Both of these vague dates chime with what I'd believed was Star Wars' release date of June-ish 1977 (it was in fact released in America on May 25th that year, and I'd always thought we'd gotten it a month or so later).
Either way, both sets of memories can't be right; either they've got it wrong, or I've got it wrong. My money had been on them getting it wrong because, frankly, they're old, and Star Wars didn't have the same sort of impact on them as it did me. Plus, I want to believe that what I remember is the truth.
In fact... it isn't. And neither is their version: both are wrong.
Star Wars didn't open in the UK until December 27th 1977 - and even then it was only in two cinemas in central London, and it stayed that way for a month or two. I've learned this troubling, foundation-rattling, truth from a book entitled The Star Wars Phenomenon in Britain, by one Craig Stevens.
It has upended everything I thought I knew about my life with Star Wars, and has confirmed that much of what I remember about Star Wars is merely the American version of its history.
The film didn't really start rolling out in the UK until early 1978. Some areas didn't get it for another ten months, while it had a staggered release from January onwards. Having dug into my local newspaper archives, I've since learned that it opened in what was then my local cinema on February 5th 1978 - which was the earliest I could've possibly seen it.
Now I'm questioning everything.
